3.1.1 Effect of plateau pika disturbance on palatable plant biomass
Plateau pika disturbance (disturbance) significantly affected the palatable plant biomass (Table 1), whereas the five sites (site) did not affect the palatable plant biomass. The interactions between site and disturbance also significantly affected palatable plant biomass. When data from five sites or an individual site were analyzed, the palatable plant biomass was lower in the disturbed plot than in the undisturbed plot (Figure. 1A; Figure. 1B).
